Map of the Communities of the Isle of Anglesey, Wales

Anglesey includes the largest island in Wales, as well as various smaller islands. Just as Anglesey is joined by bridges to the mainland, so Holy Island is linked to Anglesey. The 143 Scheduled monuments cover over 4,000 years of the history of the islands. Spread throughout the interior and especially the coast of the islands there are 89 prehistoric scheduled sites, including chambered tombs, burial cairns and standing stones, hillforts, hut circles and a henge. Six sites date from the Roman period, and seven from early medieval times. The 18 sites from the medieval post-Norman period include spectacular castles, remote dwellings, and wells, stones and churches. Finally the modern period is mainly agrarian in its purposes, but also includes the copper, coal and brickmaking industries. After a spell as part of Gwynedd, the Isle of Anglesey County now covers the same area as the historic county of Anglesey.

Scheduled monuments are found in 34 of the 40 Community areas on the Isle of Anglesey. Clusters are found in Moelfre on the eastern side (14), Trearddur on Holy Island (11), Llanidan overlooking the Menai Strait (10) and Llangoed in the far east (10). One site, Beaumaris Castle, is part of a World Heritage Site and this plus a further 22 of the monuments are in the care of the Welsh heritage agency, Cadw.

Scheduled Ancient Monuments (SAMs) have statutory protection. The compilation of the list is undertaken by Cadw Welsh Historic Monuments, which is an executive agency of the National Assembly of Wales.[1] The list of scheduled monuments below is supplied by Cadw[2] with additional material from Royal Commission on the Ancient and Historical Monuments of Wales and Gwynedd Archaeological Trust.

SH519689
'Hill of the old people' is a substantial mound with a stone chamber. Bones were found here in 1754, and along with Plas Newydd Burial Chambers (AN005) it was included in the first Ancient Monuments Act in 1882. It was excavated by W J Hemp in 1929-35, and Neolithic pottery appeared to lie under and in front of the mound, suggesting a settlement predating its use as a burial site. The chamber was given a doorway following the dig, but is not accessible to the public. It is visible from the southern edge of Plas Newydd Garden Wood. Prehistoric

SH344738
A huge capstone resting on three uprights formed a spectacular monument, described in 1865 as "one of the gems of the Anglesey Cromlechs".[25] It was excavated in 1936 and a Beaker fragment indicated the Neolithic tomb was re-used during the Bronze Age. The monument is in the care of Cadw, with public access. In recent years, the capstone cracked, since which the whole has been supported by two brick piers. Prehistoric

SH538721
This Burial Chamber on the eastern edge of Llanfair PG, (described on the schedule as 180m NE of Pen-y-Berth), has a large capstone now resting on its collapsed support stones. It was a simple passage grave, suggesting an earlier date than most of the Anglesey neolithic tombs. Prehistoric

SH519826
During sewer works in 1965 what was thought to be a small stone burial chamber was found in what is now an area of housing in Benllech. No ancient remains were found, and the presence of a medicine bottle suggested a more modern date. This left the question of what it might be. A stone goose-pen, corn drier, or a folly have all been suggested but are by no means convincing. In the absence of an explanation it retains its listed status. Prehistoric

SH514817
Limestone capstone, which appears to be a piece of the local bedrock, levered up and propped in place by other stones. The rise in ground around it may represent a 14m circular mound or cairn that originally covered it. Partial excavation by E.N. Baynes in 1909 found that 'treasure seekers had cleaned out the whole of the chamber'. Prehistoric

SH509824
Two large upright stones support a large capston, which now leans at a steep angle. It was 'plundered' in 1874 when a visitor dreamed of a crock of gold, but found only bones.[31] A full excavation by Lindsay Scott in 1933 found late neolithic and early Bronze Age burials of 54 individuals. The base of the chamber was cut into the bedrock, and the whole was covered by a mound with stone edging.[32] Prehistoric

SH425719
Three enormous boulders: two blocky and fairly upright, the other a vast slab. They are thought to be glacial erratics which have not travelled far. Striation details suggest some manoeuvering has taken place, and therefore they were probably adapted to create a huge burial tomb. Unverified 19th century reports claimed to have found an urn containing ashes and a ring of blue glass. Prehistoric

Five surviving uprights formed the walls of a small stone chamber. Three of these now support a large mushroom shaped capstone, with one stone not reaching the capstone, and one fallen down.

Two huge standing stones on a field boundary and path east of Brynsiencyn. The taller is 4.2 metres (14 ft) high, the tallest on Anglesey.

Neolithic tomb, expanded over three periods, each building a new chamber to the east of the previous, retaining the original alignment. It was noted in 1655, with 18th century plundering of the cairn and capstones, and reported finds of urns and bones. The most recent chamber, in use until 2250 BC, retains an elaborate entrance with tall upright portal stones. Full excavation in 1977-9 by Christopher Smith was followed by consolidation and good public access. Prehistoric

There were said to be upwards of 26 round huts, with low walls, paved surfaces, and an impressive selection of Iron Age and some Roman finds. Many of these huts were plundered for stone before a survey and excavations in 1871, and 1900, which found quern, coins, and copper ingots. Six hut outlines remain, and the field has been much ploughed. A possible (but doubtful) stone burial chamber has been described on the western side of the scheduled area. Prehistoric

Success in this was said to pressage being married within the year. The practice was suppressed by Revd Ellis, who also reduced the remote chapel to rubble.
